MP(3X) MP(3X) NAME itom, madd, msub, mmul, mdiv, msqrt, mgcd, mget, mput, mmov, mcmp, mexp, mpow - multiple precision integer arithmetic SYNOPSIS #include <mp.h> mint *itom(n) int n; madd(a, b, c) msub(a, b, c) mmul(a, b, c) mgcd(a, b, c) mdiv(a, b, q, r) msqrt(a, b, r) mexp(a, b, c) mpow(a, b, m, c) mmov(a, b) mcmp(a, b) mget(a) mput(a) mint *a, *b, *c, *m, *q, *r; sdiv(a, n, q, r) mint *a, *q; int n; short *r; DESCRIPTION These routines perform arithmetic on arbitrary-length inte- gers of defined type mint. The functions are obtained with ld(1) option -lmp. Pointers to mint must be initialized using the function itom, which sets the initial value to n. Thereafter space is managed automatically by the routines. Madd, msub, mmul, and mgcd assign to their third arguments the sum, difference, product, and greatest common divisor, respectively, of their first two arguments. Mdiv assigns the quotient and remainder, respectively, to its third and fourth arguments. Sdiv is like mdiv except that the divisor is an ordinary integer. Msqrt assigns to its second and third arguments the square root and remainder, repsectively, of its first argument. Mexp calculates a raised to the power b; mpow calculates MP(3X) MP(3X) this reduced modulo m. Mmov assigns the value of its first argument to its second argument. Mcmp returns a negative, zero, or positive integer if the value of its first argument is less than, equal to, or greater than, respectively, the value of its second argu- ment. Mget and mput do decimal conversion from `stdin' and to `stdout', respectively, of stdio(3). DIAGNOSTICS Illegal operations and running out of memory produce mes- sages and core images.
